Everything equals E=mc2

For in 1904, everyone in science believed that the universe was divided into two great realms. On the one hand there was the realm of energy, where winds blew, coal burned and lightning crackled. On the other hand, there was the realm of mass, where trees and mountains and paperweights, and perhaps even irritating patent supervisors, existed.

Those two realms were thought to be entirely separate. There was no link between the two.

Isn't it arrogant, how much we think we know? Surely we are only a little more advanced, in terms of all there is to know, than they were in 1904.

It's not necessarily 'arrogant', just there are certain limits to what we know. Considering where we are today, compared to 1904 - I think it's astonishing how far we progressed, but clearly it's nothing in the grand scheme of things... although moving in the right direction (science-wise anyway)

Interesting article, arifsali... thanks.
